'SEPARATOR.

Application filed March 31, 1927. Serial No. 180,048.

This invention relates to an apparatus for separating the gasiiorm content and the liquid content of a saturated fluid, as water or moisture from air, and controlling the flow of the same.

An object of the invention is to provide a structure of this character, in which the moisture or condensate, when separated from the air or fluid, will fall to a point below and be trapped below the current of incoming air, thus preventing it from being carried on with the currents, and to provide a structure wherein the surfaces of impingement of the saturated fluid will be greatly increased in a given area, so as to break the fluid up into small parts to insure the complete separation of the liquid from the air, and also a structure in which the conduit for getting rid of the moisture or water is conveniently within the body of the casing.

Another object of the invention is to provide a separator which will be exceedingly simple in construction, and one in which the air for instance, may be thoroughly dried before passing to the point where the dry air is desired, associated with means for controlling the flow of both the air and the condensates.

In the drawing illustrating the invention:

The figure is a section of the valve, with portions thereof in elevation.

Referring to the drawing the numeral 1 designates the valve body flanged at its lower end as indicated at 2, for attache ment to a reservoir or tank from which air reaches the valve, under pressure. To one side of the valve casing, is another flange 3, for the connection of the outlet or service pipe. The inlet is indicated by 4. and the outlet by the numeral 5.,

The upper part of the valve body is constituted by a head 6 held to the lower part of the body by bolts 7. The head is provided with a yoke 8, serving as a part of the means for supporting the hand wheel and valve stem as will be more particularly described.

assembled an annular chamber 12 will be formed. This chamber is entirely closed at its top, and closed at its bottom with the exception of a comparatively large drain hole or opening 13, and a series of small apertures or openings 14-, communicating with the chamber 12. The inner wall 11 is provided throughout the upper part of its circumference, with numerous small holes or openings 15, constituting nozzles. These are preferably flared, slightly from the inside of the walls toward the outside thereof. Integral with, and also forming a part of the inner wall 01' the chamber ii is a pecu liarly formed annulus 16, having a lip 17, spaced away from the inner wall of the inner chamber thus providing a pocket 17' between the lip and wall for a purpose that will presently appear. The upper end of this wall is provided with a flange 19, which overlaps the flange 20, on the outer wall of the drier. These two parts are firmly secured together by short bolts 21. The lip 17 of the annulus l6, is spaced from the inner wall of the drier to form an annular pocket 17 stated, which communicates through one or more small openings 23, with the chamber 12, between the inner and outer walls of the drier, as clearly shown, Conn municating with the opening 13 in the bottom of the chamber 12, between the drier walls is a conduit 24 formed in the neck of the body or casing. The lower end of this conduit is threaded, as indicated at 25, for the reception of a bleeder pipe 26, which pipe may lead back into the reservoir or tank, or may be so arranged as to lead to the outside thereof, to provide means for getting rid of the fluent condensate that has been removed from the air.

Surrounding the drier and spaced therefrom, is a seat ring 27 which is threaded into the valve casing as shown. This seat is pro vided at its upper inner edge, with a bevelled portion 28, shaped for contact with a similarly bevelled portion 29 on the valve disk 30. This valve disk is provided with a plurality of legs 31. which overlap and engage the outer periphery of the drier, thus serving as a part of the guiding means for the valve in its opening'and closing movements. The upper part of the valve disk is recessed, as indicated at 31, and internally threaded as indicated at 32 for the reception of a nut the valve disk. The valve I through the nut 38, and through a guide 41, and is provided with a thread 42, formed on the upper part thereof, thethreaded portion passing through a similarly threaded hub 48, of the hand wheel 44, the rotation of which wheel serving to raise and lower the valve disk to seat or unseat the valve. A space is left between the sleeve 41 and nut 38, in which suitable packing may be placed.

The upper part of the surface of the inner and outer walls on the inner side of each,

is corrugated or undulated as indicated respectively by the numerals 45 and 46, thereby within a given area providing greatly increased surfaces against which the air forcefully impinges, causing it to be broken up into small parts, and thus causing the moisture to be more readily separated from the air.

The drier is provided at intervals with bosses 47. These have sockets in them for the reception of the ends of bolts 48, whereby the drier is held firmly in position within the casing.

As shown in'the drawing, I may provide a bore in one or more of the bolts 48 as indi cated at 49, and provide a small hole 50 in the outer wall of the drier, near its bottom, to permit the water to leave the bottom of the chamber 12 through an outlet pipe 51, which pipe would be capped when it is not desired to use this form of outlet. However, when it is desired to use it, the conduit 24 may be plugged at its lower end instead of having therein as shown, a bleeder pipe.

The saturated fluid passes into the valve through the inlet 4 under pressure. When the valve is open the fluid will impinge first forcefully against the corrugated surface of the innner wall of the drier, and the moisture therefrom will fall into the pocket 17',

' from which itwill flow into the chamber 12 through the small openings 23.. The less saturated fluid will again pass through the nozzles 0r openings in the outer wall of the drier, and any moisture that has been left It will be understood that in opening and closing the valve the movement of the valve disk is never so much as to break the contact of the inner bearing surface of said disk with the outer periphery of the drier, hence all fluid that passes through the valve must pass through the holes or perforations in the walls of the drier.

It will be noted that the pocket 22, and the lower part of the chamber 12 are both below the openings or nozzles in the walls of the drier. This, as before intimated is for the purpose of removing the extracted moisture or water from the path of the currents in passing through the valve.

The term fluid throughout is used in its broadestsense, and the term corrugated in the specification and claims is intended to mean any formation of the impinging surfaces of the drier whereby the impinging surface, within a given area, is increased.

As just stated, the term fluid throughout the specification is used in its broadest sense, which of course includes steam from which obviously the separator is well adapted to dry or extract the moisture.
